Abstract: Abstract:    A method of forming a brake drum includes the steps of casting an iron cylindrical brake drum with a flange end and an open end to include a plurality of generally axially extending fins around an exterior surface thereof.  The cast-ing includes providing the fins with radially extending side walls which diverge along a length thereof from the open end to a widest distance therebetween at a predetermined location from the open end and converge along the length thereof from the predetermined location toward the flange end.  Accordingly, adjacent side walls of adjacent fins define a space there-between having its narrowest portion at the predetermined location.  A braking surface is machined about an interior surface portion of the cylindrical brake drum.  A portion of the top of the fins is machined on either side of the predetermined locations to form a cylindrical array of seats each with a shoulder located inwardly of the predetermined locations.  A steel band is formed and secured to the brake drum on the seat of the fins to encircle the brake drum at the predetermined location.

Abstract: ABSTRACT     A squeeze  formed aluminum alloy article,  such as  a piston,  is  formed  with  a  reentrant  cavity  14  with reinforced edges by locating an isostatically compacted salt core  10 and annular alumina-silicate fire pad  11 in the mound  cavity  of  the  squeeze  forming  press  prior  to introduction of the molten metal therein.  The core 14 is subsequently dissolved from the squeeze formed article to provide a  reinforced  corresponding shape  to  the  article which does not require subsequent machining.

Abstract: CUTTING TOOL WEAR MONITOR            ABSTRACT      A method and apparatus by which the degree of wear and useful life limitations of a drill, end mill or other types of boring or turning tools can be detected. The method is based on the short circuit current, open circuit voltage and/or power that is generated during drilling, boring, etc. by the utilization of an insu-lated rotary tool bit (17) to which electrical contact is made by a non-rotating conductor (37,39)  and an insulated or non-insulated workpiece, with an external circuit (41,42)  connecting the tool and workpiece (11) through a  measuring device (43).   The generated cur-rent, voltage or power shows a sharp increase or change in slope upon considerable tool wear or failure.

Abstract: ABSTRACT    In an X-Y addressable workpiece positioner, the workpiece to be positioned, such as a semiconductive wafer to be sequentially exposed at different regions thereof in accordance with a pattern of a mask, is disposed for movement with a work stage along coordinate X and Y axes.  The work stage has a two-dimensional array of X and Y coordinate addressing indicia enclosed within a border and affixed to the work stage for movement therewith. A portion of an enlarged image of the array of addressing indicia is projected onto a sensor stage to derive an output indicative of the X and Y coordinates of the array of addressing indicia relative to the position of the sensor stage.  The X and Y coor-dinates of the array of addressing indicia are sensed through addressing indicia recognition windows of the sensor stage and are differentially compared to remove unwanted background effects. Concomitantly, the border is sensed through border sensing windows of the sensor stage to provide a frame of reference for the sensed X and Y coordinates of the array of addressing indicia.  The sensed X and Y coordinates of the array of addressing indicia are compared with the X and Y coordinates of a selected addressed position of the work stage to derive an error output.  In response to this error output the work stage is moved to the selected addressed position so as to position a region of the workpiece for exposure in accordance with the pattern of the mask.  The work stage is sequentially moved to succeeding addressed positions in the same manner to position each of the remaining regions of the workpiece for exposure in accordance with the pattern of the mask.

Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus and a method for carrying out the dehydration  reaction  to produce  a  high boiling compound comprises charging a raw material and an organic solvent into a circulating system including a reactor, a preheater and an evaporator to cause the chemical dehydration reac-tion, drawing water, formed as a result of the dehydration reaction, together with the solvent in the form of vapor, compressing the vapor, effecting a heat exchange between the compressed vapor and the evaporator, dehydrating the com-pressed vapor by condensation, removing the dehydrated water out of the system, and returning the remaining solvent to the reactor.  According to the apparatus and the method, the yield of the desired product can be increased while saving energy by the use of vapor recompression technique which effectively shifts the reaction equilibrium to the reaction product side.

Abstract: ABSTRACT            The invention relates to a method and device for measuring and regulating the concentration, preferably of a fibre sus-pension, with the aid of a blade (1) pivotally suspended in the suspension.  The blade (1) is caused to pivot such that its trailing end (8) moves between two end positions (A,B) in the suspension for providing a predetermined angular stroke ( .alpha. ).  Time measurement is carried out when the trailing edge (8) of the blade (1) moves through its stroke from its upper end position (A) to its lower end position (B).  The time obtained is a parabolic function of the con-centration and varies in response to the shear force re-sistance in the fibre suspension of the blade (1) during its angular stroke, and thus in response to the concentra-tion of solid substances in the suspension.

Abstract: INFORMATION TRANSFER METHOD                    AND ARRANGEMENT     ABSTRACT           A local area network comprising a plurality of terminals interconnected by a communication bus is disclosed.  Each terminal comprises a memory, a main processor, and a co-processor.  To transmit information in communication mode, the main processor loads date into a transmit buffer area of the memory, and the co-processor reads the data from the transmit buffer area and transmits a packet on the communication bus.  Similarly, the co-processor receives data from the communication bus and stores it in a receive buffer area from which it is read by the main processor for use.  In an alternative mode, called the direct transfer mode, the co-processors are reconfigured so that data for transmission is read from the actual locations in memory where it is stored (not the transmit buffer area), and received data is stored in storage areas where it is expected to be used (not the receive buffer area).

Abstract: In a control loop for automatically adjusting variable-gain amplification, a sinusoidal signal with a frequency fo that is critical for the control loop is superimposed over a positioning parameter W. Two synchronous rectifiers S1 and S2 filter out the oscillation components of a control parameter x and of a control difference xd that contain frequency fo, and the components are compared in a comparator VL. A control and regulating circuit C continues to vary the variable-gain amplification at controls RG until the amplitudes of the oscillation components being compared in the comparator are equal. The variable-gain amplification is correct at that point. The variable-gain amplification can even be adjusted in a compact-disk player while the player is in operation.
